Actually, I'm generally not a big supporter of winter tires in Toronto. There is not enough winter in Toronto. The problem with winter tires is that they are considerably less desirable on pavement. Toronto's weather is warm enough, and most of Toronto's major streets are plowed regularly that you're on pavement the vast majority of the time anyway.
After having winter tires on my car for a few winters, I've been much happier just using with all seasons in good condition during the winter. I just drive a lot slower when there's snow out. The all seasons have somewhat less traction in the snow and ice, but are way, way better in everything else, esp. rain.
Remember, Toronto is not Quebec City or Regina.
P.S. The whackjobs are those who drive irresponsibly, and that includes a large chunk of people who have winter tires. Heck, the first people I often see on the curb after a snowstorm are those with 4-wheel drive SUVs and winter tires.
